I Application filed April 15, 1916. Serial No. 91,395.

ing s, 1 denotes an elongated member terminating at one end portion in the stationary aw 2, and at a point immediately adjacent the jaw 2 the elongated member 1 is provided with a threaded opening 3 arranged at right angles to the working face of the stationary jaw 2. 1

4 denotes a movable jaw provided at the longitudinal center of its work engaging face with a threaded shank 5 adapted to be disposed through the opening 3, wherebyit will be perceived that upon rotating the shank 5 the movable jaw 1 may be adjusted relative to the stationary jaw 2. It will be further observed that the jaw 4 affords a means whereby the requisite axial rotation may be imparted to the shank 5 and that the opposite end portions of the movable jaw are adapted for coaction with the stationary jaw 2.

At a point inwardly of the opening 3, the elongated member-'1 is provided with a second opening 6 arranged in parallelism with the opening 3 and through which is loosely directed the pin 7 having its end remote from the working face of the jaw 9. enlarged, as at 8, and coacting with the shoulder 9 within said opening 6, whereby the movement of the pin 7 under the influence of the expansible member 10 is limited. The expansible member 10 constitutes a spring adapted to encircle the pin 7 and is interposed between the jaw 11 carried by the inner end of the pin 7 and the shoulder 9.

The jaw 11 is flat and provided at one end with the outstanding flanges 12 which are adapted to be disposed at opposite sides of the removable jaw 4, whereby the shank 5 is held against axial rotation and the movable jaw 4 thereby held in an adjustment rel- 95 ative to the stationary jaw 2. It will also be observed that the jaw 11 is of such a length as to extend beyond the coacting end portion of the movable jaw a so that the same may be readily engaged by the digit of a hand for forcing the jaw 11 out of contact with the movable jaw 4i.

Pivotally engaged, as at 14, with the end portion of the elongated member 1 remote from the jaw 2, is the jaw 15 provided intermediate its length with the lateral extension 16 which is disposed within the opening 17 produced intermediate the length of the second jaw 18, the inner end of said jaw 18 terminating rearwardly of the corresponding 11 To all whom it may concern:

Be it known that 1, AUGUST VVEISLER, a citizen of the United States, residing at Sereno, in the county of Perry and State of Missouri, have invented certain: new and useful Improvements in renches, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain improvements in wrenches and it is an object of the invention to provide a device of this general character having novel and improved means whereby two relatively movable jaws may be conveniently adjusted one relative to the other and whereby said jaws may be effectively locked in their various adjustments.

It is also an object of the invention to provide a novel and improved device of this general character including a stationary jaw and a movable jaw mounted for movement in a direction at right angles to the stationary jaw together with means carried by the stationary aw for holding the movable jaw against movement.

The invention also has for an object to provide a novel and improved device of this general character wherein a movable jaw is provided with a threaded shank in engagement with the stationary aw to permit adjustments of the movable jaw relative to the stationary jaw upon rotation of the shank.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved wrench whereby certain important advantages are attained and the device is rendered simpler, less expensive and otherwise more convenient and advantageous for use, all as will be hereinafter more fully set forth.

The novel features of the invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, 1 will now proceed to describe the same with reference to the accompanying drawings, wherein Figure 1 is a view partly in plan and partly in section illustrating a wrench constructed in accordance with an embodiment of my invention; Fig. 2 is a sectional view taken substantially on the line 22 of Fig. 1; and Fig. 3 is a sectional view taken substantially on the line 3-3 of Fig. 1.

As disclosed in the accompanying drawend of the jaw 15 and connected with the elongated member 1 through the medium of the links 19, as it is believed to be clearly apiarent'that the jaws 15 and 18 are of an alligator type.

From the foregoing description, ,it v is V thought to be obvious that a'wrench conand formation of the several parts herein shown 1n carrying out my invention in practice. v j r I claim: a

I. A Wrench comprising a stationary jaw having an opening disposed the'rethrough at right angles to its working-face, a shank threaded through said opening, a movable jaw carried by an end of the shank and stationary carried by the stathe outer portion of the memwith the movable jaw for holdadapted for coaction with the jaw, a member slidably tionary jaw ber coacting ing the shank against axialrotation and means for constantly urging the outer endof the slidable member outwardly.

2. A wrench comprisinga stationary jaw the, movable jaw for holding the shank agalnst axial rotation, and means for constantly urging the jaw of thepin outwardly In testimony whereof I hereunto my signature in the presence of two witnesses.

AUGUST WEISLER.
